QBO not sending emails.

Welcome to the Community, @NickNath.

In using QuickBooks Online (QBO), there are a lot of features and one of them is sending emails to your customers. And I’d love to help you with your concern, but could you tell me more about it?

To be able to define the appropriate solution and steps to this matter. First, I’d like to ask you what specific email you're trying to send to your QBO account.

Any additional information will be much appreciated. I’ll be waiting for your response. Have a good day!

Hi Irene 

Thank you for responding,  We are trying to send invoices and estimates however we are getting a sending error.   Delivery error.   

I checked the email in the Settings.   So I am at a lost.   Please help

I appreciate you for coming back to the thread and providing an error when sending email sales entries in QuickBooks Online. I've got steps to ensure you can get this and can send invoices and estimates efficiently.

One of the troubleshooting steps to fix the error is to check your company and customer-facing email address fields. Then, ensure they are complete, have the correct format, and do not have prefixes. If you haven't performed this yet, you can do so by following the steps below.

1. Click the Gear icon ⚙, then select Account and settings.
2. Choose the Company tab.
3. Select Contact info, then check your Company email and Customer-facing email. Use these examples as a reference on what format to use:

• Correct: mycompany@mycompany.com
• Incorrect: email:mycompany@mycompany.com

Furthermore, you can also check your location’s email address you used on the sales form. 

Here's how:

1. Click the Gear icon ⚙.
2. Choose All lists and Locations.
3. Find the location you used on the invoice.
4. From the Action column, select the dropdown, then Edit.
5. Check your email address in the field “This location has a different email address for communicating with customers” and make changes if needed.
6. Click Save.
7. Try to resend your sales form.
